DragonFly recently released version 2.4, but binary packages built for the
development releases of 2.3.1 and 2.3.2 still work for it. However,
people adding these packages (especially with DragonFly's pkg_radd, which
is a wrapper around pkg_add) will get a warning about it being built for a
different version of the operating system.
The warning generates more confusion than anything, in this case, since
pkg_radd is designed to pick out the correct release's packages.
Is there a way to suppress the version warning when installing packages
via pkg_add? Alternately, is there a way to change the record for what
operating system it was built for? If there was a way to automate a
change like that, I could run it over our package collection after each
bulk build.
